MAILING-ENVELOP.

Specification of Letters Patent.

Patented Nov. 16, 1915;.

Application filed June 29, 1915. Serial No. 36,920.

To all whom it may concern:

Be it known that I, HERMAN L. Gnnvn, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, haveinvented'certain new and useful Improvements in Mailing-Envelops, of which the following is a specification.

This invention relates to mailing envelops, particularly to a form of envelop which may with equal advantage be made in large or small sizes out of flexible or stilf paper.

In the forms of envelops hitherto used for mailing third class matter, especially in the larger sizes, it has almost always been found necessary to use some special form of fastener which had to be attached to thepaper. Such a fastener not only is comparatively expensive but renders it obvious that the envelop is unsealed, making it at once apparent that the matter sent is not first-class mail. 7

' The present invention has for its object'to dispense with the-use of-the separate fastener, giving the appearance of a sealed envelop, whereas the envelop is reallyunsealed and thus may be transmitted under third class mail matter rates.

In the drawings illustrating a, few of the various forms in which my invention may be'embodied, Figure 1 is a plan view of one form showing the envelop open. Fig. 2 is a similar view showing the envelop closed. Fig. 3 is a perspective view'illustrating the parts in intermediate position assumed when the flaps are being folded to close the envelop. Fig. 4 illustratesia modified form with two sealing points instead of, one. Fig.

5 illustrates a further form in which the body of the envelop is folded. Fig. 6. is a 'view similar to Fig. 5 partly unfolded.

Figs. 7 and 8 illustrate forms adaptable for stiff paper.

Referring in detailto the drawings, particularly to Figs. 1, 2 and '3, my. improved,

envelop has extending from the front and back portions thereofatits mouth contiguous flaps 10 and 11 which are preferably tapering in outline and their lateral edges 12 and 13 respectively converge correspondingly. The edges 12 of the flap 10.preferably converge more abruptly than the edges 6' 13 of the flap 11, thus'forming an overlapping portion on the flap 11 which extends past the edges of the flap 10 and may be readily manipulated when the envelop is closed. If desired, the flap 10 may, at some point adjacent to its extremity, be tapered still more abruptly to come to a vertex-14. However, it will. be understood that the 6X- tremity may be left blunt instead of coming to a vertex.

At a suitable point on the back of the flap 10, preferably adjacent .to the vertex 14, a comparatively. small area 15 is gummed and the-flap 11 is formed'with a corresponding cutout' 16, so as to clear the gummed area 15.

When the envelop is to be closed, the flaps are together folded over along'an intermediate line 1718 as indicated generally in Figs. 1 and 3. The gummed portion 15 is moistened and then the flaps are folded over again into the position illustrated in Fig. 2,

along the line 22 so that the gummed area '15 adheres to the body of the envelop, thus is merely necessary to insert a finger under the edges 13 to pry the tongues 19, 20 from their folded position under the flap 10. The flexibility of the material will be sufficient to permit this operationto be carriediout very readily without tearing the envelop or b'reakingthe seal of the gummed portion of the flap 10 against the body of the envelop. In case the material is quite flexible, the"cut away portion 16 may be so shaped as to form horns 21 which partly surround the-gummed area 15 and serve to securely hold the sections 19 and20 under the flap '10 until they are removed by the manipulation above explained. I

In the modified form illustrated in Fig. 4, provision is made for a wider mouthed envelop. The flap may thus converge to a blunt edge 31 and the flap 32-maybe formed flap 30. Otherwise, the construction is the sameas that of the envelop first described.

In the further modified form illustrated in Figs. 5and 6, the flaps and 41 are made shorter so as to fold only once, the second fold being'made in the body of the envelop along the line 42. The portion 43 which is folded over thus has its marginal edges closed instead of open as in the forms previously described. This makes the closure of the envelop tighter and renders it suitable for holding a granular or powdered substance.

In the further modified form illustrated in Fig. 7, a construction is shown which is thereof into two tongues-53 and 54: and on each side of the gummed area'51. However, by reason of the fact that the materlal is stiff, the inturned horns ofthe other forms described are omitted and instead of tongues are formed with diverging edges 55 and 56 at the cut-away. Thus, the tongues may be readily unfoldedwhen the envelop is closed without breaking the seal, and to facilltate this, the tongues are preferably formed with corrugations 57 which render the same more flexible. v

The form illustrated in Fig. 8 is substantiallysimilar to that in Fig. 7 but with the corrugations omitted. This form isadaptable for paper which is not so stiff as that which may be used in the form in Fig. 7

It will be noted that according'to my'improved construction the flapwhen closed is 7 reinforced as it forms a plurality of. layers 7 and thus will not tear as readily as in the forms of envelops of the usual construction.

. It will be understood that various further modifications may be made without departing from the scope of the invention as defined in the accompanying claims.

Having thus described my invention, I claim asnew and desire to secure by Letters Patent:

1. A mailing envelop comprising a body having afront and back portion, flaps extending from said front and back portions at the mouth of the envelop, one of said flaps being provided with'a gummed area adjacent its extremity and the other of said fiapsbeing formed with a cut-away portion opposite said 'gummed area whereby the mmed flap may be sealed to removably hold the second flap in place.

2. A mailing envelop comprising a body having a mouth, contiguous flaps extending from thebody'at the mouth, one of said flaps 1 being formed with a gummed area and the other of the flaps being formed with a cutaway portion about the gummed area where by the first flap may be sealed'to the body: and removably hold the second flap thereto.

3. A mailing envelop comprising a body portion formed with a mouth, a pair of flaps extending from the body at the month, one of the flaps being provided adjacent its extremity with -means for attaching the same to the body of theenvelop and the other of the flaps being formed with a cut-away portion about said attachingmeans dividing the same into a plurality of sections removably held by the'first mentioned flap against the body of the envelop.

i. In a mailing envelop, abody portion havin a mouth a a1r of fia s extendin from the body of said mouth, the first of said fi'aps being provided at its extremity with means for attaching the'same to the body i of the envelop, a second flap being formed with a cut-away portion about said attach ing means dividing the second flap into a plurality of sections, the lateral edges of the second fiapoverlapping the edges .of the first flap whereby said second flap' may be readily manipulated to remove the sections from beneath the first flap without detaching the first flap from the body.

5. A mailing envelop comprising a body portion formed with a mouth, a pair .of flaps extending from the body at the mouth, one

of the flaps being provided adjacent its ex,-'

tremity with means for attaching the same to the'body of the envelop;and the other of the flaps being formed with a cut-awayipor- 'tion about said attaching means dividingthe same into a plurality of sections having pro jecting portions partially surrounding said attaching portion, said sections removably held by the first mentioned flapfagainst the body of the envelop. Y

6. A mailing envelop comprising a body portion formed with a mouth, a pairv of flaps extending from the body at'the mouth, said i flaps being adapted to be folded twiceto close the envelop, and means for sealing the interior flap to the body of the envelop to removably hold the exterior flap thereto.
